Whether you’re home or not, PetPeek Window can satisfy your dog’s curiosity about what goes on just beyond your fenced-in yard through a tough acrylic porthole of sorts. The convex window, which you install through a hole in the fence and which reaches out a bit past the yard for better viewing, enriches your dog’s outdoor experience by allowing for a wider view on the world. The dome is 9.5 inches and comes with all necessary hardware. Costs from $29.98 to $36.73 at retailers. More information can be found at www.petpeek.info.
